Coolant Smell From Air Vents.

[dirkdiggler]

I can smell coolant whenever I turn on the Heat in my 97 boxster.

it only smells when the heat is on.......otherwise no smell.

No smell with AC on either.

Is this most likely a Heater core issue?


I have been checking my Coolant level and it is not dropping so I am not sure if it is a leak or what? ..... can anything else cause it to smell through the vents?


Is the heater core super difficult to install if that is the issue?


I am very impressed with how hot of air these cars blow ..... this thing is going to be super warm and toasty in the wintertime!!!

as always, any insight is much appreciated??
